Purpose and fitment for BMW E39

The presented glass has been designed specifically for the rear right side of the BMW 5 Series E39 body, which translates into a precise fit for the door frame and factory seals. Its placement in the rear right area of the vehicle allows for seamless integration with the window regulator mechanism and other door components, without the need for structural modifications.

Thanks to the preservation of the original geometry and glass thickness, the installation process is predictable for an experienced service center, and once installed, the glass works correctly with the door guides, trim, and door locks.

Glass characteristics and color

The glass is made of green-tinted glass, typical for factory glazing in many BMW E39 configurations. This color:

• ensures visual consistency with the other windows of the vehicle,
• limits the penetration of some sunlight into the interior,
• positively influences thermal comfort and interior visibility.

Choosing the right color is important both from an aesthetic and safety point of view – uniform glazing facilitates observation of the surroundings and eliminates unwanted light reflections.

Benefits of using an original used window

Choosing an original, used side window for a BMW E39 is a sensible solution for drivers who want to maintain the factory finish standard without having to invest in expensive replacements. This type of component allows you to:

• maintain compliance with factory glass parameters and body shape,
• preserve the original character of a premium class vehicle,
• optimize repair costs after damage to the side glazing area.

Application in body repairs and renovations

The rear right side window is used primarily for repairs after collisions, mechanical damage, or acts of vandalism. It is a component that directly affects:

• the rigidity and tightness of the side body section,
• protection of the interior against weather conditions,
• safety of passengers in the rear seat.

A properly selected window allows for the restoration of full functionality of the rear door, ensuring proper closing, operation of the lifting mechanism, and adequate acoustic insulation.

Why choose an OEM component for BMW

Using original glass elements in a BMW E39 is important for both durability and the value of the vehicle. A component from the same group as factory Car windows guarantees:

• compatibility with factory mounts and seals,
• preservation of the performance properties intended by the manufacturer,
• easier integration with other body elements during body and paint repairs.
